Hi people, I've just downloaded glpk and read some documentation. I have some questions:
1. What kind of number representation does glpk use? floating point?
2. Does it deal with number overflow?
3. I read it performs preprocessing. Preprocessing will delete empty    rows/columns and convert constraints on just one variable to lower/upper bounds. But does it perform other kinds of preprocessing?
4. I want to use B&B to find only a feasible (not optimal) integer solution. How can I do it?
5. after solving LP problems with simplex method, I read, glpk stores some useful information. If I added new constraints or new variables, could I use that information to solve the new LP problem faster?
